Merge branch 'd3' into release
Conflicts:
drivers/acpi/sleep.c
This was a text conflict between
a2ef5c4fd44ce3922435139393b89f2cce47f576
(ACPI: Move module parameter gts and bfs to sleep.c)
which added #include <linux/module.h>
and
b24e5098853653554baf6ec975b9e855f3d6e5c0
(ACPI, PCI: Move acpi_dev_run_wake() to ACPI core)
which added #include <linux/pm_runtime.h>
The resolution was to take them both.
